My invention is a hair rinse preparation,

' in water form a rinse water. I may usedyes which with the acid will dissolve in water or dyes held in suspension. My specific In preparation comprises tartaric'acid with a coal-tar or vegetable dye mixed in suitable f proportions, and generally sold in the form of powder, to be dissolved by the user whe'n wanted.

M rinse powders-are preferably usedafter the air has been shampooed,'thoro ughly washed and rinsed'in clear water. -the'n the rinse tint is applied to the hair by immersing the-hair in the rinse or dipping it over the hair until all or nearly all of the color has been taken out of thewaterr This is 'afinal application to the hair and it isnot supposedto be rinsed, but if it is found that the hair has absorbed too muchof the color it may be:

25,:partly washed out witha clear waterfrinse. After treatment the hairshould bewelldried and brushed to bring out; theluster. My invention is not tobe confused with hair dyes which give a perm-seasa10r'ae; ha.1m whether sold in powder or liquid form. The preferred proportions are ten pounds of commercial tartaric acid crystals or powder mixed with three teaspoonsful of the dye and made into a owder. I may use enna, suflicient to give a slightly reddish tinge, or the coal tar equivalent thereof. I may use various colors or mixture of colors to secure the effect. The color should be chosento harmonize with the hair and hei hten or increase its natural tint. Thus for ark brown hair a dark (1 e would be used, a slightly reddish dye muc fainter'than henna may be used to give a olden'brown efl'ecti It wi 1 be understood that the proportions may be changed, both of tartaric acid and of the dye to give the desired effect. The rinse powders are preferably sold in packages with directions for dissolving in water, which manifestly may be varied in quantity 5 as also: the stren h may be varied by using two or more pow era. 1

The rinse is used, as before described, as a final application after the hair has been shampooed and rinsed, to give a faint tint or ghnt to the hair. The action of the tartarlc acid'is to soften the water, but it has a more important function in that it partially fixes 'the dye in the hair. In the latter respect, its action is not pronounced, but does. no ,.result in the retention of the glint longer than it wouldt be retained if the acid were not Ikslainizacid a coal tar dye.

2. A hair rinse owder comprising a crys- 'mildorgan cacid, and a, coal tar dyg. 3. A" hair rinse powder comprisin sub stantiallyten pounds of tartaric aci d and'lo three teaspoonsful of a coal tar dye.

. 4. A hair rinsepowder comprising substantially ten pounds of a crystalline mild organic acid, and a coal tar dye.
